Cling Film

Linear Low-Density Polyethylene (LLDPE) serves as the primary raw material resin for the global food-grade cling-film market, valued for its superior tensile strength, puncture resistance, and high clarity compared to traditional Low-Density Polyethylene (LDPE).

Polyvinyl Chloride (PVC) remains a critical upstream material for commercial and industrial catering cling-wraps due to its exceptional oxygen and moisture permeability characteristics, although it represents less than 10% of the broader single-use food packaging volume globally.

Polyisobutylene (PIB) or similar liquid-like low-molecular-weight polymers are critical upstream functional additives blended into polyethylene resins during the extrusion process to act as tackifiers, imparting the necessary self-adhesive 'cling' properties to the film.

Ethylene monomer, the foundational chemical feedstock for both LLDPE and PVC cling-film resins, is primarily sourced upstream through the petroleum refining and distillation of fossil crude oil or natural gas liquids.
